Beyoncé was on cloud nine after her history-making performance at Glastonbury on Sunday. Moments after coming off stage, a beaming B could hardly contain her excitement when reflecting on the career milestone.

“I’m completely high. It’s so surreal what just happened,” she told Lauren Laverne and Jo Whiley. “This is like a highlight of my career.”

The global superstar had been preparing the headlining set for about two months in advance. “I don’t normally do festivals and 175,000 people, and I was very nervous,” she said. “And everyone gave me so much love and I will never, ever, ever, ever forget this.”

She sent over the 90-minute set list to festival veteran and Coldplay frontman Chris Martin for approval, and believes that Jay-Z’s headline-making performance in 2008 opened the door for her.

“I was able to see my husband perform here a couple years ago and it was one of the most exciting nights for me, and I don’t know if I would have been asked to come if he didn’t do the performance,” revealed B.
